I have not read up on your thread, but i have used MH light to remove chlorophyll. It gives off a little UV. HPS will not give off as much, sorry if this is repeated.
check out rosin, i have a video check it out.
My rosin press is the best thing I have ever purchased. Solvent - less, QUICK and easy. What is better then that? Most cannabis cups now will only let you enter Rosin made concentrates. ITS THE NEXT MOVEMENT!
I have had no less then 10% return on OLD OLD cannabis. Smashing 7 Grams in a 2.5 X 4 bag works great. They turn into great cartridges with great terp flavor. Its also ALL NATURAL. Pre-Press if you go above 7 grams for best results. Humidity is a factor in your cannabis. 62% - 65% seems to yield...
